Another newbie question from yours truly. The clouds are starting to clear so hang in there with me.
Bought some bulbs at the local Radio Shack, they have a rating of 7.5V, 220ma.
So does this mean that they are 1.65W bulbs ? I'm assuming that the maximum voltage that should be applied is 7.5V correct ? Or can I apply 9V and the current will drop to 183ma ?
I'm confused.
Next question, a switch has a rating of 1.5A at 250VAC. Eh ? Can I do more current at a lower voltage ? What about DC current, does that make a difference ?
Thanks. Trying to avoid a shocking experience.
